Summary
When Orange.fr experiences email delivery issues, a multi-faceted approach is required. Initially, monitor the situation through Orange.fr's communication channels, ESP status pages, and social media for updates and expected recovery times. During the outage, temporarily hold or throttle email sending to Orange.fr to avoid overwhelming their servers and potentially being rate-limited. Analyze SMTP error codes and Non-Delivery Reports (NDRs) to diagnose the specific causes of failures, such as temporary issues, spam filtering, or authentication problems. Implement a separate segment for Orange.fr recipients to isolate deliverability problems and minimize the impact on other domains. Use email verification tools to check the validity of email addresses and reduce bounces. Regularly check your IP address and domain against email blocklists to ensure they are not causing delivery issues. Communicate transparently with Orange.fr recipients regarding the delivery delays and keep them updated on the situation. For temporary failures (4xx errors), implement retry logic with exponential backoff. Set up bounce processing to automatically remove hard-bouncing Orange.fr addresses.
Key findings
- Monitoring: Continuously monitor Orange.fr's status, ESP updates, and social media for the latest information.
- Sending Adjustments: Pause or throttle sending to Orange.fr to avoid overwhelming their servers.
- Diagnostic Analysis: Analyze SMTP error codes and NDRs to pinpoint the cause of delivery failures.
- Recipient Segmentation: Isolate Orange.fr recipients into a separate segment to manage deliverability issues.
- Address Verification: Verify email addresses to reduce bounces, especially during server issues.
Key considerations
- Retry Logic: Implement retry logic with exponential backoff for temporary failures (4xx errors).
- Bounce Processing: Automatically remove hard-bouncing Orange.fr addresses to protect sender reputation.
- Blocklist Check: Regularly check IP address and domain against blocklists to ensure they are not causing deliverability issues.
- Transparent Communication: Keep Orange.fr recipients informed about delivery delays and expected resolution timelines.
- Code Interpretation: Understand and act upon bounce codes returned by Orange.fr during the incident.
What email marketers say
12 marketer opinions
When Orange.fr experiences email delivery issues, it's crucial to take immediate action to minimize impact. Initial steps include monitoring the situation through Orange.fr's official channels, Brevo's and Mailjet's status pages, and social media for updates. If a widespread outage is confirmed, pausing or throttling email sending to Orange.fr recipients is recommended to avoid overwhelming their servers. Additionally, examine SMTP error codes for diagnostic clues and segment Orange.fr recipients to prevent deliverability issues from impacting other domains. Finally, transparent communication with recipients about potential delays and providing updates is advised, while verifying email address validity can help reduce bounces and improve overall deliverability.
Key opinions
- Monitor Status: Track Orange.fr's status pages, Brevo/Mailjet status pages, and social media for updates on the incident.

- Segment Recipients: Segment Orange.fr recipients to isolate issues and prevent impacts on other email providers.
- Verify Email Addresses: Use email verification tools to ensure addresses are valid, reducing bounces.
Key considerations
- Retrying Delivery: Implement retry logic to automatically re-attempt sending emails after Orange.fr's servers recover.
- Bounce Processing: Set up bounce processing to automatically identify and remove non-existent Orange.fr addresses.
- Blocklist Check: Verify your IP address and domain are not on email blocklists.
- Communicate Transparently: Inform Orange.fr recipients about potential delays and provide timely updates.
- System Status: Monitor Orange.fr's system status and any official communication from them regarding service interruptions.
Marketer view
Email marketer from GMass Blog advises creating a separate segment for Orange.fr recipients. They explain that this allows senders to pause or throttle sending to that specific domain without affecting deliverability to other email providers, minimizing the impact of Orange.fr's issues on overall campaign performance.

What the experts say
2 expert opinions
When Orange.fr experiences email delivery issues, analyzing bounce codes is critical. A 4xx error signifies a temporary failure, prompting retries with exponential backoff. Carefully examine bounce codes for specific insights into whether the issue stems from temporary server problems, spam filtering, authentication failures, or other factors. This analysis guides decisions to retry sending, modify practices, or remove addresses.
Key opinions
- 4xx Error: A 4xx error code from Orange.fr indicates a temporary delivery failure.
- Bounce Code Analysis: Examine specific bounce codes for insights into the root cause of delivery issues.
Key considerations
- Retry with Backoff: Retry sending emails with exponential backoff after a temporary failure.
- Adapt Practices: Adjust sending practices based on specific bounce code insights to address underlying issues.
- Address Removal: Remove problem addresses based on bounce codes that indicate permanent failures.
Expert view
Expert from Word to the Wise recommends paying close attention to the bounce codes returned by Orange.fr during an outage. They explain that specific codes will give insight into whether the issue is temporary, related to spam filtering, authentication, or other problems. Use this information to determine whether to retry, adjust sending practices, or remove addresses.

What the documentation says
5 technical articles
When Orange.fr encounters email delivery problems, documentation emphasizes several key actions. Firstly, understand that 4xx SMTP codes signify transient failures, suggesting retrying delivery with exponential backoff as per RFC 5321. Analyzing Non-Delivery Reports (NDRs) for diagnostic codes is crucial, as they offer clues to the reason for failure, whether mailbox issues, spam filtering, or temporary server problems. Monitoring Orange.fr's system status, as recommended by PowerDMARC, keeps users informed about the issue's nature and duration. Implementing bounce processing (SendGrid) removes hard-bouncing Orange.fr addresses, safeguarding sender reputation. Lastly, implementing retry logic (AWS) ensures emails are re-attempted post-resolution, maximizing delivery chances.
Key findings
- Transient Failures (4xx): 4xx SMTP codes from Orange.fr indicate a temporary issue suitable for retries.
- NDR Analysis: Analyzing diagnostic codes within NDRs is essential for identifying the root cause of delivery failures.
- System Status Monitoring: Monitoring Orange.fr's system status and communications provides updates on the problem.
Key considerations
- Retry Logic: Implement retry logic to automatically resend emails after Orange.fr's servers recover.
- Bounce Processing: Set up bounce processing to automatically remove hard-bouncing addresses, improving sender reputation.

Technical article
Documentation from RFC 5321 (SMTP Standard) defines 4xx SMTP reply codes as representing transient failures, meaning the message *might* be deliverable if re-attempted later. The documentation recommends that sending systems should retry delivery after a delay. The specific delay is left to the sender's discretion but suggests exponential backoff.
